I recently bought the truck and noticed that there is a hesitation and vibration when pressing on the gas pedal. After a second or so the truck starts rolling. This only happens when cold. It rarely happens when the motor is hot. Dealer just changed the spark plugs, coils, (tune up), oxygen sensor. Transmission shop checked the trans. And it is in perfect shape. Check engine light hasnt turned on. What could it be?
